Well Water being neutral against Ice makes perfect sense; Water doesn't actually melt ice, but rather the temperature. The boiling point of water is 100C, and the freezing point is 0C. Anything above the freezing point will melt ice. Meanwhile, Ice is very, very good offensively. I just cannot see them taking away one of the few types that resist it.
Ice resisting Bug because "bug can't live when it's cold" is pretty far-fetched. Insects and spiders can live in harsh environments, but if these two types were to have any connection based upon this logic then perhaps it would be Ice hitting Bug super-effective.
I don't think Ice should gain any resistances, as it is an amazing type offensively and it just makes sense for each and every type. Fighting types can break ice, Fire can melt, Rock can smash, and Steel can break. Let's just be content that it doesn't have a Ground-type weakness, too. What we really need to demonstrate how the Ice-type is amazing offensively, is an Ice/Electric and Ice/Fighting Pokemon. Oh yeah, and a more powerful physical Ice move for fast Ice-types. Ice Punch doesn't cut it. Imagine Mamoswine with a 120 BP recoil Ice move. Pretty scary, considering even Skarmory takes 52.1% - 61.7%.
